Last night, I went to school. It was natural. I no longer felt throbbing or regretful. The street lights were very bright on the main road in front of the teaching building. I used to like walking under the shade of trees because the yellow light made me feel very hot. But no more. Xiaohui and Yinyin and I walked past one street light after another. We talked about the present and the future, but did not talk about the past. Everyone has accepted this fact. We have all walked out of that door and there is no way to look back. The past is just pure memories with warm light. Maybe it's still a story with great content, so I can probably write about you or us. When I forget, I get old or bored, I can talk about memories or if I meet one day and I can't remember the name for a while, I can also use it to cheat.
